PROBLEM TO BE SOLVED: To provide a bogey type track roller device hardly causing a crawler derailment even in a largely irregular ground, and a crawler type traveling device equipped therewith. SOLUTION: This bogey type track roller device comprises a longitudinal pair of track rollers 23 and 24 relatively vertically rockably mounted on the lower surface side of an endless crawler track frame 15. This device comprises a track link guide part 22a suspended adjacently to the lateral side surface side of a crawler link 51 along the lateral side of the one-side track rollers 23 and 24 from the supper shaft bogey part of the track rollers 23 and 24. The rocking radius of one bogey part having a track link guide part 32a is set larger than the rocking radius of the other bogey part. The bogey type track roller device is set in a mounting position for parting the endless crawler track frame 15 to the front side and rear side from the center, and the half bogey sides having the track link guide parts 22a and 32a are arranged toward the center side of the endless crawler track frame 15 and mounted in a symmetric form.
